AXIS 213 - Video and Audio Streams
Using Motion JPEG
The basic transmission method of audio used in conjunction with Motion JPEG video
streaming is transmission over HTTP. The video and audio streams are not
synchronized when using Motion JPEG so the streams may be slightly out of sync.
The latency in any stream should be low, but this will depend on the network
infrastructure.
Using MPEG-4
When using MPEG-4, audio is streamed using the same protocol as the video stream.
When audio is transmitted using MPEG-4, the Axis product sends synchronization
information along with the streams to the client that is performing the
synchronization.
Audio is streamed from the client to the server over HTTP when using Motion JPEG
and MPEG-4.
Accessing the Audio Streams
In addition to accessing audio in the Live View page using AMC, audio from the
Video Server can also be accessed in the following ways:
HTTP-API
You can read about accessing audio for the other protocols through the HTTP-API at

QuickTime/Windows Media Player
It is possible to use QuickTime and Windows Media Player to listen to the audio
stream using the same methods to access video streams.
